雾计算是云计算的延伸概念,可以使计算和存储功能更接近应用程序和医疗信息数据源.提出了一种基于雾计算的区块链医疗数据管理架构,医疗数据所有者的元数据存储在私有区块链上,支持搜索和防篡改功能,并允许雾节点以分布式方式执行授权过程.案例研究表明,与其他方法相比,本研究所提出架构可以缩短患者医疗数据访问时间,满足可靠性和互操作性要求,为病历资料管理理论和实际应用提供借鉴.

In public health emergencies, the collection of archival information in the area of public health emergencies is very important, which can provide a reference for the early warning and processing mechanism.At the present stage, the unlimited demand of archival users for resources and the convenience of obtaining resources have become the two driving forces to promote the "transformation" and "growth" of archives.Public health emergencies, the transformation of archives collection and service mode, social media has become an indispensable platform for user information exchange, sharing and transmission, which requires archives to change the mode of archives acquisition and storage.Archival users require more interactive, targeted and cutting-edge forms of access and archival services are also developing toward diversified functions and connotations.Archival information resource sharing is also an important link in this development trend.This paper attempts to analyze the collection methods of archives departments in public health emergencies, and then puts forward the corresponding measures for archives departments to play their functions, such as flexibly solving the needs of archives access, strengthening the development of information resources, doing a good job in the collection of relevant archives, and publicizing archives work in combination with hot spots.This paper discusses the completeness of archival data collection, the means of archival management, the scientific classification of archival data, the ways of archival data collection and so on.
